I am going to start with ARM development (after 2 years of AVRs) and have picked up the STM DISCOVERY board with the stm32f4 microprocessor on it.
I have decided to go with eclipse + ARM gcc since I don't like the code limit on Keil and I don't have the money to get a paid version.
Following the tutorials I have installed eclipse along with gcc ARM tools + openocd + make utils etc.
My question is about the 'packages' plugin. Like every beginner, I am confused as to whether to use new STM HAL or the older SPL.
My understanding is that HAL has implemented abstraction to a level where it can be referred to as Arduino equivalent for arm. SPL on the other hand provides just enough abstraction to make coding faster but you still need to deal on chip level.
With this understanding I would like to stick with SPL to understand things better rather than using HAL.
What I would like to know is, does using packages for STM implicitly force me to use HAL? If so, can someone point me on how to use SPL with my setup?
